The present inventionrelates to side door constructions.-

More particularly the present invention relates to the doors of railway house cars of the type commonly called automobile cars. House cars for the shipment of automobiles or other bulky lading require a particularly wide door opening. Cars of this sort are commonly provided, in addition to the usual sliding door, with a secondary or supplementary door, which second or supplementary door is slidably movable to provide a door opening of extraordinary width, but which may be'stationarily held when a door opening of such extraordinary width is not required. In order to lock said supplementary door in its closed position, it is common to provide a movable door jamb which maybe secured to said supplementary door or may move independently of said supplementary door. capable of movement longitudinally of the car and should have means for locking same in position. Certain types of door jamb for i said supplementary doors have provided means for holding a nailing strip for the securing of grain doors such as are used in lining the car when the car is used for the purpose of carrying grain or other finely divided lading. It is common to provide the jamb of the su plementary door with latching members or latching the jamb in door closing position.

An object of thepresent invention is to provideza, construction involving a supplementary door and a door jambtherefor, which jamb requiresa minimum of kinds of fittings. A further object is to provide a door jamb involving relatively simple parts which include castings at the top and bottom of said 'amb, which castings may be identical, therey simplifying the matter of stocking repair parts.

A further object is to provide a door jamb having socket members at its top and bottom, which socket members provide housings for latching members and which house the two extremities of a wood filler post.

A further object'is to provide a door amb of great strength, which will afford protection proceeds.

In either case said jamb' should be.

tion to the means foroperating the latches above referred to.

A further object is to provide a socket member which may be used either at the top or bottom of the jamb and whichwhen used at the bottom of the j amb permits the ready removal and replacement of the latch at the bottom of the jamb.

Further objects will appear as the descrip- Referring to the drawings,.

The numeral 12 indicates in its entirety, a movable door jamb which in the construction illustrated is a metal ,jamb. .Said j-amb is secured to the supplementary door 13. Said jamb is, adapted to be moved with a movement of translation longitudinally of the car along with said supplementary door 13. Figure l illustrates a the jamb' 12 in its home or door closing; p

The other flange 25 may take the form of a reinforcingbulb f The Z-bar 22 "has an improved section modulus over a plain angle and thereby permits theuse of a: relatively light weight shape, which"relativelyllight shapehas the? advantages thatffabrlcation and handling aresimp ified'; "As will be pointed out here I Linafter, the flange orbulb 25 has the further advantage that it protects the operating ,ofthe latching mechanism of the car from v d'amagedue to shifting ladi'n'g. The extremi that the rolled shapev 22 presents a reentrant angle toward the interior ofthe car and towardthe opening controlled by the main "door'27 (see Fig. 8), this construction havthis pass on certain latching ing the advantage that the filler post and nailing strip 28A inayjbe ohamfered off, as

indicated in Figure 8'by the line 2813, to provide 3 a maximum of space to permit the clearance of hubs andffenders; of auto1nobiles inserted diagonally int of the house car.

Disp osedat the top and bottom of the j amb '12 are theshousings or socket members 29"29, which aresidenticial and a pre'-' jferred embodiment of the'presentinvention takethe form of castings. Thexwood fillers post 28 is gained into said castings 2929 at the two ends. of said] strip 28. 'qEigures 4, 6, 7 and 9 show one of the castings 29 in the position it; assumes when used at the bottom of the j'amb 121- "Ittvill benoted that said casting 29-includes asocketportion 30 iniwhich the filler post" 28 is disposed, said filler post 28 having a reduced end portion 7 31 for this purpose. One wall 32 of the casting-29 is provided with a pair of holes 33 -33 for the reception of rivets or bolts for'seouring said wall .32 to the web ofthe rolled shape 22. Each of the walls 34 34 adj acent. to the wall 32 is provided \viththe hole 35. In thefcase of a casting 29 used atthebottom ofthe jamb 12, one of said holes 35 is used "for receiving a rivet or bolt; for securing the corresponding wall to the flange 2a of the Z-ba-r 22L='-In'the case of" a castingused at the top-of the jamb 12, the oth'er ofsaid holes 351s used for securing the corresponding Wall 34*to the flange 24 of thejZ-bar 22*. 1 j

and? it will be noted'that the extremityof the casting 29 spaced from the walls 32 or 34'3 i is provided with the pair ofli'p portions36, which extend'toward one another and are adapted to have overlapping relationship with the shoulders 171-7 of the de tent members 14: and 15 at the bottom and top of the car.

Referring to the sectional view illustrated inFigure T, the inner conformation ofeach side wall 341s illustrated. The two side Walls 34 are identical, so that a descriptionof one of said side walls will suflice for both. It will be noted that theinner surface of each wall 34 is provided with projections forming a pair of sockets'3'7 and 38, which-sockets provide bearings. for latching members 39 and top of theljamb 12..

willbe noted that the'socket portions 3'? and'38 have restricted entrancesf iland 42, respectively. Theltrunnions 4sand' 44 of the latch members 39 and 40,fres ectively, are I provided with flat-faces", where y said trunnions 43 and li be admitted through said entrances41 and42,f*respectively, when the latches areturnedat predetermined angles.

The flat faces of the trunnions 43 are indicated by the. numerals 45%45; A flat face on the trunnion 44 is indicated by the numeral 46. Said 'fiat faces 45 -45 and 46 are so disposed upon the trunnions 43 and 44, re-

' they cannot assumewith the door amb and the dete-nts 14 and 15 in normal {positions within the car and with the'filler post 28 in position.

The latches 39 and 40 are connected tooneanother by means of the latch operating bar 47. The details of the bar 47 need not be described herein, the subject matter of a similar latch operating bar being described and claimed in the Tobin and Darrow Patent No. 1,533,621, issued April 14,1925. It will be suflicient to state that the. bar 47 causes the latching members 39 and 40 to move in unison, whereby the jamb 12 will either be in latched condition at both top and bottom, or in unlatched condition at both top and bottom, dependingupon movement of said bar. 47 The lower latch 39 is provided with the holding cam 47A, which forms'no part of the present invention and need not be described herein.

It will be noted from an inspection of Figure 8 that the flange or bulb 25 of the Z-ba-r 22 is in position to protect the operating bar 47 against shifting lading within the car.

With particular reference to steel door construction, attention is directed to the reinforcing plate 48 secured along one edge to the door 13 by means of a row of rivets 49 and along its other edge to the web of the Z-bar 22 by means of a row of rivets 50. Said reinforcing plate 48 not only strengthens the construction, but prevents lading from getting into the corner between the door 13 and the web of the Z-bar 22. The front edge of the door 13 and the flange 24 are secured together by means of the row of rivets 51. The rolled shape 22, the reinforcing plate 48 and the front edge portion of the door 13 thereby form a trusswork which effectually protects the door jamb against twisting The filler post 28 is secured to the rolled shape 22 by means of bolts 52 and 53.

Though the filler post- 28 may be a permanent part of the jamb, it may be desired to remove said filler post in case said filler post becomes injured and to insert a new filler post. In order to remove said filler post 28 i without requiring the dismantling of the castings 29-29 from the Z-bar 22, or removing the jamb proper from the door to which it is riveted, the filler post 28 may be cut transversely, as indicated by the numeral 49'. After removal of the holding bolts, the

two extremities of the filler post 28 may be" readily removed and other sections may be mounted in place, the bolts being reinserted to secure the two sections of said filler post in rigid relationship with the Z-bar 22.

As appears from the drawings, each housing or socket member 29 is open from top to bottom, this construction having the decided advantage that in case it should be necessary to remove the latch 39 at the bottom of the jamb and replace same with another, the change can be made very readily without taking the 'car out of service. Though the latches are ordinarily quite sturdy, breakage of the lower latch may occur if'said latch is subjected to very' rough treatment. To change a lower latch 39, the filler post may be removed in a manner referred to above,

and the jamb maybe moved to a. position free of the detent 14, such for example as the position illustrated in Figure 9.
